Question
Sumit covered a distance of 1000 km in 5 hours on a
bike. How much distance will he cover on a bicycle in 7 hours if he rides the bicycle at 2/5th of the speed of the bike?Solution
Distance covered on bike= 1000 km, Time = 5 hrs. Speed = (Distance )/Time = (1000 )/5 = 200 km/hr. Time = 4hrs, Speed of bicycle= (2 )/5 × 200 = 80 km/hr. Distance covered on bicycle= Speed × Time = 80 × 7= 560 km.
